I've recently added several larger gridded Deep-Cut mats to the shop. These 6' x 4' approximate (1800mm x 1200mm) cloths are printed with a light 10cm grid (not shown), and are a particularly convenient size for larger grid-based games with smaller scale miniatures, such as 15mm/10mm/6mm. These can also be purchased without the grid, as shown below, or with different grids (15cm/20cm).
I've also received a big restock this week, and as of today, I have all the mats I stock available in all the different sizes and different grids.
These Deep-Cut mats are printed on a light cloth and can be washed, ironed, and folded or rolled away for storage. Hills can be placed on top or even, if shallow, underneath. These mats (together with the plains, fields, steppe, desert and wasteland mats) can all be found in The BigRedBatShop.
